Terry Rozier went a little off script when asked what he learned from appearing in a Game 7 last season. The question clearly intended to gauge what Rozier could carry with him from his experience. Instead, the Celtics guard offered a reminder of how unpredictable basketball can be, shouting out Kelly Olynyk for his monster performance to down the Wizards last year.

In other words, nothing about Saturday night’s Celtics-Bucks Game 7 will follow a script. Olynyk, now with the Heat, won’t be there to rescue Boston with a fourth quarter to remember, but any number of role players could step up to push their team into the next round. Maybe Marcus Smart will shake off his Game 6 struggles to take a game-deciding charge in the final minutes. Maybe Tony Snell will forget his early series woes to drill a number of 3-pointers for the Bucks. Maybe Giannis Antetokounmpo will duel with Al Horford while Khris Middleton and Jayson Tatum match each other with difficult perimeter...
